“In cotton I was very successful in my trading for a long time. I had my theory about it and I absolutely lived up to it. Suppose I had decided that my line would be forty to fifty thousand bales. Well I would study the tape as I told you, watching for an opportunity either to buy or to sell. Suppose the line of least resistance indicated a bull movement. Well I would buy ten thousand bales. After I got through buying that, if the market went up ten points over my initial purchase price, I would take on another ten thousand bales. Same thing. Then if I could get twenty points’ profit, or one dollar bale, I would buy twenty thousand more. That would give me my line–my basis for my trading. But if after buying the first ten or twenty thousand bales, it showed me a loss, out I’d go. I was wrong. It might be I was temporarily wrong. But as I have said before it doesn’t pay to start wrong in anything.

As I think I also said before, this decribes what I may call my system for placing my bets. It is simple arithmetic to prove that it is a wise thing to have the big bet down only when you win, and when you lose to lose only a small exploratory bet, as it were. If a man trades in the way I have described, he will always be in the profitable position of being able to cash in on the big bet.

I recollect Pat Hearne. Ever hear of him? Well, he was a very well-known sporting man and he had an account with us. Clever chap and nervy. He made money in stocks, and that made people as him for advice. He would never give any. If they asked him point-blank for his opinion about the wisdom of their commitments he used a favourite race-track maxim of his: “You can’t tell till you bet.” He traded in our office. He would buy one hundred shares of some active stock and when, or if, it went up 1 per cent he would buy another hundred. On another point’s advance, another hundred shares; and so on. He used to say he wasn’t playing the game to make money for others and therefore he would put in a stop loss order one point below the price of his last purchase. When the price kept going up he simply moved up his stop with it. On a 1 per cent reaction he was stopped out. He declared he did not see any sense in losing more than one point, whether it came out of his original margin or out of his paper profits. (more…)
